Have you been here?

Barcelona’s contemporary art museum (known as MACBA) focuses on mid-century abstraction and European Pop. Richard Meier designed the building—its glass exterior stands out against the mostly Gothic-style buildings in the area—in the Raval neighborhood, the city’s former red-light district, which has seen major revitalization since the early 90s. There’s no permanent collection, so even if you’ve been, it’s always worth another visit.
